SPECIFICATION forming part of Letters Patent No. 772,710, dated October 18, 1904.

Application filed January 11, 1904. Serial No. 188,593. (No model.) i

f To all whom it may concern.-

. Be it known that I, GEORGE VICTOR ELLIs,a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Sewer-Lift, of which the following is a full, clear, and ex- This invention relates to, an apparatus intended especially for use in sewerage systems toeject the sewage from a temporary receptacle therefor located below the sewer-level.

The invention is useful in various other connections, as will be apparent to skilled mechanics. For instance, it may be employed in marine vessels to'eject water therefrom lying at a levelbelow the water-line of the vessel. The invention-comprises a certain novel arrangement by which when the sewage reaches a predetermined level in the reservoir or tank a valve is automatically opened and by the action of steam, air, or other compressed fluid the contents of the tank will be forced out thereof. In the preferred form of the invention, which is illustrated in the drawings, provision is rnade for exerting an air-pressure directlyon the sewage to force it out of the tank and for setting in operation a steamejector which sucks out the sewage. Either, or indeed both, of these devices may be employed at will.

- This specification is an exact description of one example of my invention, while the claims define the actual scope thereof. v

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a vertical section ofthe invention.

The tank or receptacleis preferably formed in two cast sections a and a, securely connectedtogether by a flanged joint 64 and the lower section having an integral skirt forming a base (0 from which passes a dischargepipe (0*, also east integral with the parts a and (0 Joined suitably to an integral thimble a, projecting from the base-section a of the tank, is the inlet-pipe 5. The said thimble a is provided with a clack-valve 0, seating to prevent the return of the sewage to the inletpipe 7), and the inlet-pipe is provided with a 5 gate d of any suitable form, arranged to move transversely across the pipe 6 completely to close it."

cl indicates a spring which serves to open the gate (Z, and 6Z2 indicates afluid piston and cylinder having connection with the stem of the gate, so that upon charging the cylinder with a fluid under pressure the spring d will be overcome and the gate d moved into closed position. These devices a? and d are the same in general principle as the automatic valveoperating devices disclosed in my prior patent, No.681,048, for automatic starting apparatus granted August 20, 1901.

(3 indicates a vent-pipe passing from the top 5 of the tank and commanded by a valve f, to which is applied a spring f, tending to open the valve. WVith the stem of the valve is connected a cylinder and piston f so arranged that upon charging'the cylinder with fluid 7 under pressure the spring f" will be overcome M and the valve f will be seated. These parts f and f also are essentially the same as the automatic valve-operating devices disclosed in my prior patent referred to. Leading to the upper part of the tank is thefluid-pressure pipe g. This pipe according to the preferred embodiment of my invention is arranged to conduct compressed air into the top of the tank to bear on the sewage therein and force the sewage from the tank. through the discharge-pipe a), as will be hereinafter fully set forth. The pipe 9 is commanded-by a valve it, to which is applied a spring it tending to close the valve. 7

7&2 indicates a cylinder and piston connected to the stem of the valve h and arranged so cock lc a pipe Z passes to the cylinder and. piston (1 this pipe having a branch Z leading to thecylinders and pistons f and It, so that when the pressure of the pipe 6 is communicated to the pipe Z and branch Z the gate (Z and valve f will be at once closed and the valve it will be opened, thereby closing the supplypipe Z) and vent and admitting the pressure of the pipe g to the tank a to force out the liquid contents thereof.

The discharge-pipe a is joined to a continuation on, passing horizontally and thence upwardly and having a clack-valve m therein to prevent backflow. Rising from the pipe m between the valve m and the tank is a Vertical elongated tank or stand-pipe a, in which is arranged a rod 0, carrying at its lower end a fixed bucket 0 and at its upper end an inverted bucket or hell 0 the latter having a limited sliding movement on the rod and when not water-borne being supported by a shoulder a, formed on the upper portion of the stand-pipe or tank a. The rod 0 projects through the top of the stand-pipe or floattank a and is connected to a counterbalanced lever fastened to the stem of the valve Zr. Normally the valve 7 stands with the pipe Z in communication with the exhaust-port of the valve. As the liquid sewage rises in the stand-pipe or float-tank n and lifts the bell or float 0 the valve Z; will be thrown to place the pipe Z in communication with the pipe a, and the pressure of the latter pipe will then act on the sewer-lift, as before explained. As the water falls in the stand-pipe a the bell 0 will seat itself on the shoulder a and relieve the rod 0 of its weight, and owing to the counterbalance on the lever 7a the valve Z: will be retained in its position until the water falls below the level of the bucket 0, whereupon the weight of the water remaining in the bucket will overcome the force of the lever Z) and return the valve to its normal position i. 0., that in which the pipe Zcommunicates with the exhaust of the three-way cock.

Located in the discharge-pipe m is an ejector or other pump 19, with which communicates a steam-pipe q. The steam-pipe q is commanded by a valve 1', seated by a spring 0' and having a cylinder and piston r connected with its stem, so that upon charging the cylinder the valve will be opened. Leading to the cylinder and piston r is a pipe 8, branching from the pipe Z, and both of said pipes are fitted with globe-valves t, by which either pipe may be opened or closed at will. By closing the pipe 8 and opening the pipe Z the apparatus may be-operated by compressed air from the pipe g and by opening the pipe 8 and closing the pipe Z the apparatus may be operated by the steam-ejector 11.

It should be observed that while I prefer to employ air-pressure in the pipe r and steam in the pipe qother fluids under pressure may be used instead at will.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.
